Premiere Pro includes a variety of audio and video effects that you can apply to clips in your video program. An effect can add a special visual or audio characteristic or provide an unusual feature attribute. For example, an effect can alter the exposure or color of footage, manipulate sound, distort images, or add artistic effects. You can also use effects to rotate and animate a clip or adjust its size and position within the frame. You control the intensity of an effect by the values that you set for it. You can also animate the controls for most effects using keyframes in the Effect Controls panel or in a Timeline panel.

You can create and apply presets for all effects. You can animate effects using keyframes and view information about individual keyframes directly in a Timeline panel.

Fixed effects

Every clip you add to a Timeline panel has Fixed effects
pre-applied, or built in. Fixed effects control the inherent properties
of a clip and appear in the Effect Controls panel whenever the clip
is selected. You can adjust all of the Fixed effects in the Effect
Controls panel. However, the Program Monitor, Timeline panel, and
Audio Mixer also provide controls that are often easier to use.
The Fixed effects include the following:

Because Fixed effects are already built in to each clip, you
need only adjust their properties to activate them.

Premiere Pro renders Fixed effects after any Standard effects
that are applied to the clip. Standard effects are rendered in the
order in which they appear, from the top down. You can change the
order of Standard effects by dragging them to a new position in
the Effect Controls panel, but you can’t reorder Fixed effects.

If you want to change the render order of Fixed
effects, use Standard effects instead. Use the Transform effect
in place of the Motion effect. Use the Alpha Adjust effect in place
of the Opacity effect, and the Volume effect in place of the fixed
Volume effect. While these effects are not identical to the Fixed
effects, their properties are equivalent.

Standard effects

Standard effects are additional effects that you must
first apply to a clip to create a desired result. You can apply
any number or combination of Standard effects to any clip in a sequence.
Use Standard effects to add special characteristics or to edit your
video, such as adjusting tone or trimming pixels. Premiere Pro includes many
video and audio effects, which are located in the Effects panel.
Standard effects must be applied to a clip and then adjusted in
the Effect Controls panel. Certain video effects allow direct manipulation
using handles in the Program Monitor. All Standard effect properties
can be animated over time using keyframing and changing the shape
of the graphs in the Effect Controls panel. The smoothness or speed
of the effect animation can be fine-tuned by adjusting the shape
of Bezier curves in the Effect Controls panel.

Note:

The effects listed in the Effects panel depend on the actual
effect files in the language subfolder of the Premiere Pro Plug-ins
folder. You can expand the repertoire of effects by adding compatible
Adobe plug-in files or plug-in packages available through other
third-party developers.

Clip-based and track-based effects

All video effects—both Fixed and Standard effects—are clip-based.
They alter individual clips. You can apply a clip-based effect to
more than one clip at a time by creating a nested sequence.

Audio effects can be applied to either clips or to tracks. To
apply track-based effects, use the Audio Mixer. If
you add keyframes to the effect, you can then adjust the effect
either in the Audio Mixer or a Timeline panel.

Effect plug-ins

In addition to the dozens of effects included with Premiere
Pro, many effects are available in the form of plug-ins. You can
purchase plug-ins from Adobe or third-party vendors, or acquire
from other compatible applications. For example, many Adobe After
Effects plug-ins and VST plug-ins can be used in Premiere Pro. However,
Adobe officially supports only plug-ins that are installed with
the application.

Any effect is available to Premiere Pro when its plug-in file
is present in the common Plug-ins folder:

GPU-accelerated effects

Some effects can take advantage of the processing power
of a certified graphics card to accelerate rendering. This acceleration
of effects using CUDA technology is a component of the high-performance Mercury
playback engine in Premiere Pro.

For Premiere Pro system requirements, including a list of graphics
cards that are certified as providing CUDA acceleration of effects
in Premiere Pro, see the Adobe website. For lists of various
categories of hardware compatible with Adobe Premiere Pro, see the Adobe website.

Jeff Sengstack provides detailed tips for optimizing a computer
system and Premiere Pro for performance on the Adobe website.

Information about whether a clip can be processed by the CUDA
hardware acceleration portion of the Mercury Playback Engine depends
on the dimensions of image and on the available GPU memory. For
details, see this page on Todd Kopriva’s Premiere Pro work area blog.

The CUDA processing features of the Mercury Playback Engine also
speed up and improve some things other than effects, including scaling.
See this page on Todd Kopriva’s Premiere Pro work area blog for details.

This forum post goes into detail about
what the Mercury Playback Engine is and how Premiere Pro uses CUDA.

High-bit-depth effects

Premiere Pro includes some video effects and transitions
that support high-bit-depth processing. When applied to high-bit-depth
assets, such as v210-format video and 16-bit-per-channel (bpc) Photoshop
files, these effects can be rendered with 32bpc pixels. The result
is better color resolution and smoother color gradients with these
assets than would be possible with the earlier standard 8 bit per
channel pixels. A 32-bpc badge appears
to the right of the effect name in the Effects panel for each high-bit-depth
effect.

To enable high-bit-depth rendering for these effects, select
the Maximum Bit Depth video rendering option in the New Sequence
dialog box.

For instructions on filtering the effects in the Effects panel
so that you can easily find high-bit-depth effects. See Filter
effects by type.

Note:

32-bpc effects render at 32 bits per channel only when
every effect in the render pipeline is a 32-bpc effect. If you place
an 8-bpc effect into a sequence that contains a 32-bpc effect, Premiere
Pro renders all the effects in the sequence at 8 bits.
